Sanitary comb

ABSTRACT

A hairdressing comb comprising teeth merging into a relatively wide back which has a longitudinal depression therein communicating with spaces between the teeth, the depression extending down into the mid range of the length of the teeth. The depression is wider at the back of the comb than at its bottom where it intersects the spaces between the teeth, and the sides are curved at least in the area of the bottom of the depression at the tooth intersection.

ABSTRACT: A hairdressing comb comprising teeth. merging into arelatively wide back which has a longitudinal depression thereincommunicating with spaces between the teeth, the depression extendingdown into the mid range of the length of the teeth. The depression iswider at the back of the comb than at its bottom where it intersects thespaces between the teeth, and the sides are curved at least in the areaof the bottom of the depression at the tooth intersection.

SANITARY coMs the free ends of which are largely conventional but whichare much broader toward the roots, merging into a wide comb back, thecomb back being recessed longitudinally, the recess intersecting theteeth and the spaces between the teeth so as to provide a plurality ofdischarge orifices from the recess to the spaces between the teeth, forthe purpose of r'eceivingmaterial to be spread on the hair as the combis used.

It is an object of the invention-to -provide a comb of this character inwhich the recess hasa smooth nonjointed curved bottom area which iseasily cleaned.

()ther objects and advantages of the invention will appear hereinafter.V

Reference is to be had to the accompanying drawings in which:

FIG. 1 is a view in side elevation showing the comb;

FIG. 2 is a bottom plan view thereof looking in the direction ofarrow 2in FIG. 1;

FIG. 3 is a top plan view thereof looking in the direction of arrow 3 inFIG. 1;

FIG. 4 is an end view looking in the direction of arrow 4 in F IG. 1 onan enlarged scale, and

FIG. 5 is a section on line 5-5 of FIG. 1.

Looking at FIG. 1, the comb seems to have the appearance of aconventional rat tail comb but having a split end at and 12 for thepurpose of rolling curls and the like. The individual teeth l4 have theappearance of normal teeth except that their roots extend for a greaterlength than usual and the back edge which is apparent in FIG. .1 at 16is narrower than usual in a direction parallel to the teeth. 1

As a matter of fact, however, the back of the comb as well as the rootsof the teeth in the area at 18 are relatively greatly widened in adirection transverse of the comb as clearly apparent from the otherfigures, the teeth 14 widening out to a relatively great extent in themid area thereof represented at 2%, on convexo-concave curves asshown inFIGS. 4 and 5, and the handle of the comb is made to suit tapering downto the points ill and 32 as indicated at 22.

The back of the comb is relatively deeply recessed inwardly from itsextreme edge toward the roots of the teeth to merge with the wider androot area of the teeth, and the resultant recess is indicated generallyby the reference numeral 24. It will be seen that by reason of the factthat the teeth are long, they intersect the recess throughout arelatively elongated area which is indicated at 26.

It is therefore clear that a fluid deposited in the elongated recess 24has ready access to leak through the orifices indicated at 28 in FIG. 3to the area of the teeth that are narrowedto a more or less conventionalshape, and therefore this fluid is deposited upon the hair of the'personbeing dressed.

-Most lotions have a relatively high degree of viscosity and thereforethe fluid does not just run through the comb but tends to leakrelatively slowly in the desired direction, and the comb may be used topick up the fluid by a spooning action, if desired.

It will be noted that the depression has a curved bottom at 30 and thatthe sidewalls thereof at the interior at 32, 32 are slanted downwardlytoward the bottom and merge smoothly into it. This enhances the freeflow of all of the fluid located in the recess, and it also makes therecess very easy to clean simplyby holding the same under the water tapor by the use of a brush and it will be appreciated that if thesidewalls 32 were parallel, and the bottom at 30 straight across atright angles thereto, it would be difficult to clean out the recess.

We claim:

l. A readily washable comb comprising a back portion having a deeprecess therein with spaced teeth formed integral with the back portionand extending upwardly into the back portion and downwardly below therecessed back portion, said recess in the back portion being permanentlyopen at the top to permit ready access of liquid from a tap into therecess and having slotted openings in the sides and bottom thereofcommun cating with thespaces between the teeth, whereby on applicationof a liquid to the back portion the comb may be readily cleaned, theliquid running out from the recess between the teeth so that the spacesbetween the teeth are flushed out, the recesshaving smooth, unimpededwalls and bottomto assist in the free flow of the liquid.

1. A readily washable comb comprising a back portion having a deep recess therein with spaced teeth formed integral with the back portion and extending upwardly into the back portion and downwardly below the recessed back portion, said recess in the back portion being permanently open at the top to permit ready access of liquid from a tap into the recess and having slotted openings in the sides and bottom thereof communicating with the spaces between the teeth, whereby on application of a liquid to the back portion the comb may be readily cleaned, the liquid running out from the recess between the teeth so that the spaces between the teeth are flushed out, the recess having smooth, unimpeded walls and bottom to assist in the free flow of the liquid.
